Toyota 90910-12204 Valve, Duty Vacuum Switching

The Active Control Engine Mount is a component that generates vibrations to cancel out engine vibration and reduce noise at idle. It operates using a Diverter Valve that utilizes engine vacuum to vibrate a diaphragm within the mount. This vibration is then transferred to a liquid inside the mount, which in turn transfers the vibration to the mount's rubber pad, effectively canceling out the engine vibration. To replace the VSV, the two vacuum hoses and the large hose connected to it must be disconnected and labeled for proper reassembly. The valve's mounting bolt and electrical connector are then removed, followed by the disconnection of the remaining hose. The installation process is the reverse of the removal steps.

To begin with, the EVAP canister purge valve is a component located behind the air filter housing on four-cylinder models and on the left end of the front bank cylinder head on V6 models. To remove it, the engine cover(s) must be removed first, then disconnect the electrical connector and EVAP hoses from the purge valve. The EVAP canister requires raising the vehicle and securely placing it on jack stands. Next, the fuel tank needs to be removed by disconnecting the electrical connector(s) and hoses from the Vapor Canister. The electrical connector from the leak detection pump module also needs to be disconnected. To replace the canister you must loosen the three mounting bolts and any other wiring harnesses. Installation is the reverse of removal. Lastly, the leak detection pump can be removed by following the steps to remove the EVAP canister. Installation is the reverse of removal.

The purpose of the Active Control Engine Mount is to generate vibrations to cancel out engine vibration and reduce noise at idle.

No, the location of components within the EVAP system can vary depending on the model year and vehicle. Different components might need to be serviced based on the specific model.
